One of the google container builder step fails, as it depends on a file generated from the previous step.

Does all the steps in buildspec get executed in one machine? Please suggest if there is a better way to do this or if I need to add any extra step in the build spec?

buildspec:

steps:
- name: 'gcr.io/cloud-builders/mvn'
  args: ['install:install-file', '-Dfile=locallib/wlthint3client.jar', '-DgeneratePom=true',  '-DgroupId=com.oracle.weblogic', '-DartifactId=wlthint3client', '-Dversion=10.3', '-Dpackaging=jar']
- name: 'gcr.io/cloud-builders/gradle'
  args: ['build']

STEP 0: Install a JAR directly in to maven local repo

STEP 1: Gradle build which has a dependency on this JAR

Below the logs from cloud builder where step 0 is successful and step 1 is not,Step 1 unable to find the jar installed by step 0:

With my experience what I have understood is in google container builder each build step is getting executed in different VMs. So I fixed the above issue by modifying my build spec.

Build Spec with single step to upload artifact and to build the project.

 steps:
 - name: 'gcr.io/cloud-builders/gradle'
   args: ['uploadResultArchives','build']
